How to recover deleted branch in github

Asked by At

One of your teammates accidentally deleted a branch, and has already pushed the changes to the central git repo. There are no other git repos, and none of your other teammates had a local copy. How would you recover this branch?

Once you find the commit you're looking for, create a new branch from it and you're done!

$ git checkout -b branch-name 70b3696
Switched to a new branch 'branch-name'

I assume the developer still has his local repo, right? The terinal should have the id of the revision when he pushed the removal... use that ID to create a new branch

git branch blah the-id

If the terminal is already closed, then check git reflog for the last revision of that branch.

Easiest - look into "git reflog" of the teammate's local repo. You'll find last entry when he checked-out the branch last time.

If it's lost locally, you may have access to remote repo - look there for dangling commits. See instructions here: https://softwarebakery.com/recovering-commits-with-git

Just create a new branch on top of the found commit-id

Below command will show the list of commits

git fsck --full --no-reflogs | grep commit

Choose the commit from the deleted branch and checkout
